IPC: C04B41/52
Filed: 1988-03-09
Abstract: A nitride ceramic member (14) is maintained at a vacuum of 1 x 10⁻⁴ Torr or less at a temperature of 1,100°C or more, and a metal vapor is brought into contact with the surface of the nitride ceramic member. A nitride is reacted with the metal in the surface portion of the ceramic member (14), and a metallized layer is formed on the surface of the member. If AℓN is used as a nitride ceramic material (14), the AℓN member is maintained at the vacuum at the high temperature and a Ti vapor is brought into contact with the surface of the AℓN member to form a TiN coating layer on the surface of the AℓN member. A BN or graphite mask is formed on the surface of the nitride ceramic member and the above method is practiced to selectively form a metallized layer on the non-masked member surface. By selectively forming a metallized layer by using AℓN, a highly thermal-conductivity substrate (20) having a conductive layer (22) formed on the AℓN base can be prepared.

Abstract: Thin film field effect transistors are disclosed having direct or near direct contact of the source and drain electrodes to the channel region. Inverted gate (Fig. 3d) and non-inverted gate (Fig. 4e) types are fabricated by forming metallic source and drain electrodes (54′, 56′; 78, 80) within a layer of semiconductor material (46; 68) in contact with the channel region. The electrodes are formed by converting monocrystalline, polycrystalline or amorphous silicon regions to a refractory metal such as tungsten by using a non-self-­limiting metal hexafluoride reduction process. The tungsten conversion process is isotropic and provides self-alignment of the source and drain electrodes with the gate in the non-inverted gate TFT. The process is low temperature, allowing the use of amorphous silicon as the semiconductor material. The transistors are especially useful for formation on large glass sub­strates for fabricating large flat panel displays.

Abstract: In a process for producing polycrystalline layers (3) having coarse crystalline structure, a thin interlayer (2) of amorphous material of the same type is deposited before the deposition of the polycrystalline layer (3) to avoid crystal structure effects originating from the substrate (1) and said interlayer (2) is then recrystallised (4) with the polycrystalline layer (3). As a result of the amorphous interlayer (2) any influence due to the fine crystalline structure of the substrate (1) is reliably avoided and the thin-layer technology can also be applied to polycrystalline silicon layers, which is of great benefit, in particular, in the production of solar cells. <IMAGE>

Abstract: In a cell analyze apparatus, a light beam is irradiated onto cells (or particles like the cells) flowing through a flow cell so as to measure cell light information for each cell with respect to a plurality of parameters (for example, the forward scattered light intensity, the right angle scattered light intensity and the intensity of fluorescence by different dye). Eased on a minimal point of a histogram associated with the cell light information with respect to one or more parameters, the cell population is subdivided into fractions. When the minimal point is missing in the histogram, the parameters above are converted by use of a predetermined conversion expression (for example, a coordinate conversion is effected on the parameters) such that a minimal point is detected from the histogram of cell light information related to the new parameters obtained by the conversion, thereby subdividing an objective cell population.

This method can be carried out by an apparatus which preferably comprises two parabolic mirrors (4, 5), a laser (9) emitting a laser beam (10) such as to originate from the focus of one of said mirrors and a detection mean (8) positioned in the focus of the other mirror. The food products (11) are moved between the mirrors, for example by a conveyor belt (1, 2).
